TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 607,405, dated July 12, 1898. Application filed June 24.1395. serial No. 558,854. (No model.)

T0 at whom it may concern:

Be it known that I, ERNEST A. BRIGHAM, a citizen of the United States, and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Margin Stop and Release for Type-\Vriting Machines, of which the following is a specification.

The object of my invention is to provide simple and effective marginal stop contrivances and also releasing mechanism therefor; and to this end my improvements consist in the several features of construction'and combinations of devices hereinafter more fully described, and particularly pointed in the appended claims.

In the accompanying drawings, making a part of this application, and in which similar letters of reference indicate corresponding parts, Figure 1 is a plan view of my invention as applied to one description or style of type-writing machines. Only those parts of the type-writing machine which are essential to the understanding of my invention and its operation are shown. Fig. 2 is a side elevation of the mechanism for effecting at the keyboard the release of the marginal stop. Fig. 3 is a view, partly in elevation and partly in section,of the adjustable margin stop for stopping the carriage when traveling from right to left, the sectional part of said figure being taken at the dotted'line 3 3 of Fig. 1. Fig. 4 is a front end view of the adjustable stop shown in and a side elevation of the free end portion of the lever operating the bell hammer or clapper and stop employed in connection with the said lever. Fig. 5 is a view, partly in elevation and partlyin section, taken similarly to that of Fig. 3 and illustrating the construction of the adjustable margin stop for stopping the carriage when traveling from left to right, the section being taken on the dotted line 5 5. Fig. 6 is afront end view of the device shown in Fig. 5.

My device is applicable to various typewriting machines; but for the purpose of illustration I have shown it applied to the Remington type-writer.

In the drawings, A indicates the frame of the machine.

B indicates the frame of the carriage, in which the platen C'is mounted.

D D are the wheels of the carriage, running upon tram-rail D The carriage is further steadied in its horizontal reciprocatory movement by means of an arm D having an eye D engaging stationary rail D fixed to the frame Aof the machine. I provide a rod E, in the present illustrative'instance being a separate rod from the one indicated by D and located in the rearv of the latter. This rod is notched at intervals corresponding to the dis tance of the letter-spacing. There are two rows of such notches. In the present illustrative instance one row of said notches E is at the side thereof and the other row E at the bottom thereof. This rod E is suspended in the arm F of the crank-arm F. The crank arm or lever F has ahorizontal arm F and a vertical arm F, whose free end is pivoted at 70 F to the upper end of a vertical connecting rod F, the lower end of the latter being pivoted at F to the rear end of lever F horizontal, or nearly so, pivotally fulcrumed at F to the frame of the machine and at its other or forward end provided with a vertical finger-key F The crank F is fulcrumed on a rod G, rotatable in bearings G. at the respective endsof the machine, the crank capable of being adjustably set at a desired point along the rod Gby means of set-screw F Depression of the key F operates to vibrate the rodE laterally forward, and as soon as the pressure upon the key F is released the rod E will return to its first position. This return of the rod E is accomplished not only by the weight of the connecting-rod F, but by the weight of other parts hereinafter described.

Located on the rods E and G is the adjustable margin stop II for stopping the carriage in its movement toward the left, thereby determining the stopping-point at the righthand side of a sheet. This adjustable stop consists as follows: It has a portion H 9 5 through which pass the rods G and E. In this same portion H is located a ratchet latch or pawl H whose tooth or projection H is arranged to engage one of the rows of notches. The preferred mode of releasing the tooth I1 I00 from the notch consists in the means shownto wit, a vertical reciprocatory bar H playing through a bearing H of the portion H of the stop and also through a spring H", one end of which lies in and bears against the bottom of the opening H of the portion H while the top portion of said spring bears against the thumb or push button 11 of the bar I1 By depressing the button H the operator of the type-writer releases the tooth 11 from engagement with its adjacent notch, thereby releasing the stop H and enabling the stop to be moved along the rods G and E to any desired point thereon. The portion H carries the arm H and at the free end of this arm is an angulated arm J, pivoted at J to the free end of arm 11 and having a vertical arm J at the left-hand end of the arm or lever J and a weighted portion J at the right-hand end of the armJ.

Beneath the central portion J 5 of the lever is a stop J which prevents the portion J J from being depressed beyond the line of the stop, and consequently prevents the arm J from yielding when its right-hand edge is struck; but this stop J obviously does not prevent the arm J from yielding when its left-hand edge is struck.

Near the central portion of the carriage, at its rear side, is located a stop K of any suitable form. One description of such stop of my invention is that shown, and consists of the U-shaped bar having two limbs, respectively marked K K The arm K passes through a sleeve K of the carriage-frame B, while the arm K constitutes the stop proper and is in alinement with the reciprocatory oscillatory arm J, hereinbefore described.

In the sleeve K is a set-screw K arranged to impinge against the arm K of the stop. By this set-screw the stop K can be adjusted, so that the arm J 3 will be struck by the stop somewhat sooner or later, according as the stop K is adjusted. Thus the stop K is adjustable, so that whenever the adjustable stop H is in any given notch it will be struck by the stop K when a letter-space has been completed.

I will now describe the functions and operation of the stop II.

Upon the rod G is a scale corresponding to the notches of the lower rod E and also to the letter-spacing of the type-writer. The operator, by means of the latch arrangement H 850., releases the stop Hand moves it along the rod G, so that it will stop the carriage at the desired point upon the scale, thereby enabling the type-writing to stop at the same point upon the page and make an even margin of the lines at the right-hand end thereof. As the carriage moves from right to left the stop K passes under the part J and strikes against the right-hand side of the vertical arm J This arm J immediately stops further movement of the carriage from right to left. This stop J is also arranged to operate the bell mechanism and give the alarm before the carriage has reached the limit of its movement toward the left.

A bell L is located in the carriage, preferably low down, as shown. In connection with the same is a clapper L operated by an arm L having a bent portion L and ahorizontal arm L and extending out into the path of the angulated arm J. This arm L is pivoted at L to the frame of the carriage and is also provided with a stop L". The purpose of the stop L is well known-via, to prevent the clapper from resting directly upon the bell and yet allow the latter to be so near the hell that when the arm L is depressed and released the weight of the clapper will be sufficient, through the elastic nature of the arm L to carry the said clapper down against the bell and ring the same.

In operation, as the carriage moves from right to left the arm L of the bell-lever passes under the part J and strikes against the arm J and the latter, unyielding in the direction in which it is pushed by the arm L depresses the latter. After the arm L has passed beyond the arm J 3 the arm L is free to rise and the clapper L falls and rings the bell. WVhen the carriage is moved from left to right in order to begin another line, the arm L strikes the rear side of the arm J 3 of the lever J and forces it from left to right, thus enabling the arm L to pass by the stop J 11 and be in position to again ring the bell.

The adjustable margin stop for stopping the carriage on its return or right-hand travel is constructed as follows: I have indicated this stop generally by the letter M, and it has a portion H similar to the stop 11 and an arm H similar to the arm H of the preceding stop. The part II is supported by and is capable of being slid on the rods G and E just as part H of the stop II is. This stop is provided with mechanism for latching and unlatching it similar in all respects to the mechanism shown in connection with the stop H, with the single exception that while the stop H employs one of the rows of notches on the bar E stop M employs the other row of these notches in connection with its own latch. It is immaterial which row of notches the one stop has as distinguished from the other stop. For instance, the stop H might employ the lower row of notches,while the stop M might employ the side row of notches. In the present instance the latch of the stop 11 employs the side row of notches E and that of the stop M employs the under row of notches E", for which purpose the latch 11 extends underneath bar E, substantially as shown in Fig. 5.

By the construction and arrangement of the catches or fastening devices the marginal stops H and M may be vibrated Without separating or disengaging the catches or fastening devices or freeing or unlocking said marginal stops, thus avoiding any accidental disturbance of their adjusted positions and the possibility of failure to relock or reengage on the returning vibratory movements of said marginal stop.

The free end of the stop M is provided with a pivotal stopping device N, substantially as follows: Portion N carries the end bearings M M Pivot M supported in these bearings or uprights,carries sleeve N located between bearings M M". This sleeve and bearings are connected to a suspensory stoppiece N This suspensory stop-piece rests against the edge of the arm H and is prevented from OS- cillating from left to right, and its free end is as obviously free to oscillate from right to left and away from the arm H The functions and operation are as follows: The operator by means of the push-button H releases the stop and sets it by means of the scale on the rod G' and the notches and latching mechanism aforedescribed at the desired point upon the scale, so as to regulate the distance from the left-hand edge of the page at which the printing shall begin. The operator then moves the carriage from left to right until a stop, as P, fixed to the carriageframe, impinges against the suspensory stoppiece N. The carriage will then be stopped and the machine is in readiness for the operator to begin the line to be written.

I have described the functions of these two stops H and M so far as their limitations of the movement of the carriage are concerned after they have been set and without being disturbed by human agency. It often occurs that the operator desires to increase the length of a line previously determined by the setting of the adj u stable stops. In such event should the operator desire to diminish the blank margin of paper at the beginning of the line in other words, to begin the line earlier than the regular margin of printed workhe depresses the key F. This operates to throw the rod E forward and as a result lifts the free end of the lever M, with its suspensory stop, upward and out of the way of the path of the stop P, and thereupon the operator can move to the right of stop P as much as he desires. The suspensory stop-piece N will not interfere with the movement of the carriage from right to left, because when the stop P strikes against the right-hand side of the suspensory stop-piece N it is free to yield,

and its yielding will allow the stop P to pass under it without detention.

In case the operator desires to extend the line beyond the established right-hand margin of the printedcolumn as determined by the stop H J, he depresses the key F and thus raises the free end of the stop H J out of the path of the stop K and allows the latter to pass under the arm J When the carriage is again moved from left to right to begin another line, the angulated arm J J J will yield, the part J being pushed from left to right and the part J 4 returning the part J 3 to its normal position after the stop or contact device on carriage has passed by the combined carriage-stop and bell-trip J be appreciated by experts inthe art.

The rod G preferably rotates in bearings,

although of course it may be fixed or station- I lators H and M when the vibratory rod E is actuated to swing said stops. The stops II and M may be vibrated about said rod G by direct application of the hand to said stops.

Among the various advantages not hereinbefore already mentioned may be specified the following: The margin stop can be released at the keyboard by the depression of either of the keys F This capacity of use is a great advantage in rapid writing and will Heretofore the operator in releasing the margin stops in use has been compelled to lift his hands from the vicinity of the keys and up over the machine. By my invention such labored and tardy work is entirely obviated. It is as easy to release the margin, stop as to print a letter.
